Injury forces Ivanovic out of Olympics
French Open tennis champion and top ranked Olympic seed Ana Ivanovic has been forced to pull out of the Beijing tournament due to a thumb injury.
The Serbian player was due to face Mariya Koryttseva of Lithuania in her first round match.
"This is one of the worst moments of my career," Ivanovic said Sunday at a news conference.
Ivanovic said she sustained the injury while training after Wimbledon, where she was a surprising loser in the third round.
She has played just two competitive matches since, losing in Montreal to Tamira Paszek of Austria at the Rogers Cup.
Ivanovic took over the No. 1 ranking in women's tennis when Justine Henin surprisingly retired in the spring. She will be knocked off that perch by Jelena Jankovic of Serbia when the next Women's Tennis Association rankings come out on Monday.
Ivanovic said she still hopes to play at the U.S. Open in New York, which gets underway on Aug. 25. Her injury opens up her side of the draw in Beijing, which includes Serena Williams of the United States and Elena Dementieva of Russia.
Serena Williams ahead in halted match
The first day of Olympic tennis was a bit of a washout. Nine matches were completed, 10 suspended and 26 postponed, which means a heavy backlog for the tournament.
Serena Williams of the United States was leading Olga Govortsova of Belarus 6-3, 2-1 when the match was suspended for the night. Williams won gold in 2000 with sister Venus in the doubles competition.
Italy's Francesca Schiavone was a winner in one of four women's matches that were completed Sunday at the Olympic Green Tennis Centre.
Schiavone, who is ranked 26th by the WTA, was a 6-4, 6-2 winner over Uzbekistan's Aqkul Amanmuradova.
Caroline Wozniacki of Denmark beat Selma Sfar of Tunisia 6-4, 6-1, Australia's Sam Stosur defeated Italy's Sera Errani 6-3, 6-2 and Bulgaria's Tsvetana Pironkova was a 6-3, 6-4 winner over Marta Domachowska of Poland.
